RUG- MANUFACTURE.

Application filed March 13, 1922. Serial No. 543,194.

To all whom it may concern:

Be it known that I, CHARLES F. BACON, a citizen of the United States ofAmerica, residing at Toledo, Lucas County, Ohio, have invented new anduseful Rug Manufacture, of which the following is a specification,

This invention relates to the production of flat fabrics. V

This invention hasutility in the conversion of thread stock into heavymaterials as hangings, rugs, mats, etc.

Referring to the drawings Fig. 1 is a fragmentary view of an embodimentof an apparatus which may be used in carrying out certain features ofthe invention herein; i

Fig. 2 is a fragmentary view of a heavy flat product hereunder which maybe used as a mat, rug, or table covering;

Fig. 3 is a fragmentary view of a warp assembly of the materialhereunder; and

Fig. 4 is a diagram of the series of steps in connection with theinvention herein.

From a single light thread 1, which may be of single ply, a substantialheavy stock material may be produced hereunder. This thread ispreferably knitted into a fabric of a warpless character by the loopingof the thread backward and forward in the production of open or meshmaterial. This is most economically produced in a knitting machine forproducing tubular stock 2 which may be of considerable diameter. Thistubular stock 2 may be delivered to a machine 3, herein shown as drivenby pulley 4: on shaft 5 carrying a picker or napping roll 6 for fiuflingor fleecing one side of flat tubular stock 2 when passing therethrough.This shaft 5 is shown as carrying gear 7 in mesh with gear 8 on shaft 9for driving follower or picker roll 10 effective for fluffing or nappingthe opposite side of this tubular stock 2 from that napped by the roll6. Accordingly this tubular stock 2 in passing through the picker rollsis napped on the outer side onl l he gear 8-is effective to drive gear13 on shaft 14 carrying rotary knivesor slitters 15 operating inopposing relatlon to the 11 driven by gear 11" from the gear 13.

Upper friction rolls 12 are driven at the same rate of speed as therolls 11 through the gearing 12.

These more or less narrow strips upon being drawn orstretchedlongitudinally have a tendency to compact or curl. this pullingautomatically brings about a frictional holding of the loops upon eachother so there'is a positive and effective holding of the strip stockagainst fraying. Accordingly by this pulling there is produced a rollwhose margins are not exposed for weakening of this roll or stripfabric.

, This strip may at one be used in the production v of a heavy fabric inthe uncolored thread as used originally in forming of the tube 2.Furthermore the thread 1 may have been dyed before being incorporated inthe tube 2. When desired the napping step may be omitted; However whenthe napping step is incorporated there Furthermore is an added tendencyfor the rolling up of the outside thereby more effectively bring ingthe'margin into the central position of the roll or strip 17 ofsingleply from the cut pairs from the tube 2.

In instances where a mottled or particolored effect is desired, thestrip material 17 may be twisted into a hank and'such dyed and then whenuntwisted the stock 17 is colored only in such places as were exposed onthe outer side of the hank in the dyeing operation.

The stock 17, whether or not dyed "by twisting, may be incorporated as acontinuous strip of woof in the warp 18,say as produced by loom whichmay be of the type of Newcomb Patent 663,357 of Dec. 1, 1900. Thecontinuous character of the stock 17 allows the continued travel of theshuttle from side to side to carrythe woof 17 about bends 19. There isthus produced a smooth, flat, knotless stock or finished product of rugor mat type. I

In the building up of these strips 17 from the tubular stock 2,successive tubes may be sewed together and such sewed places disappearin the strip material as treated to braided stock incorporated withadditional assembling means as threads 21, 22, providing a zigzag stitchinstead of the additional assembling means as shown as warp 18.

Whether or not napping has occurred in the preparation of the stripstock 17, 18, warp assembled woof 17 or braid assembled material 20 maybe napped on one or both sides in the finished product.

There is tensile strength in the simple cord as herein knit assembled inthe production of heavy stock and such stock is of a smoothness andsubstantial character in the finished product as materially tocontribute to the life thereof. Changes'in the steps as indicated makepossible wide ranges in the production ,of the stock for variousutilities.

hat is claimed and it is desired to secure by Letters Patent is 1. Inthe production of a flat textile material of heavy body, the knitting ofa strip,

multiplying the strip into a plurality of longitudnal sections byslitting, extending by stretching a continuous section thereof to effecta closing in of the fabric to determine its body and automaticallyminimize marginal fraying, and assembling into a flat product.

2. In the production of fiat textile mate rial of heavy body, theknitting of a strip. multiplying the strip into a plurality oflongitudinal sections by slitting, a closing in of the fabric todetermine its body and automatically minimize marginal fraying, andincorporating binding thread means for assembling into a flat product.

3. In the production of flat textile material. of heavy body, theknitting of a strip, multiplying the strip into a plurality oflongitudinal sections by slitting, napping one side of the material,extending by stretching a continuous section thereof to effeet a rollingof the napped side out to bring the edges therein to minimize marginalfraying, and assembling into a flat fabric.

4. In the production of flat textile material of heavy body, theknitting of a strip. multiplying the strip into a plurality oflongitudinal sections by slitting, twisting into a bank, dipping thehank into a dye, and untwisting.

5. In the production of flat textile material of heavy body, theknitting of a strip. multiplying the strip into a plurality oflongitudinal sections by slitting, extending by stretching a continuoussection thereof to effect a closing in of the fabric to determine itsbody and automatically minimized marginal fraying, braiding, andassembling into a fiat fabric.

6. In the production of flat textile material of heavy body, theknitting of a strip,

multiplying the strip into a plurality of longitudinal sections byslitting, extending by stretching a continuous section thereof to effecta closing in of the fabric to determine its body and automaticallyminimize marginal fraying, braiding, and assembling the braided materialinto a flat fabric by zig-zag sewing.

7. A heavy body fabric of light thread embodying stretched knittedcontinuous strips with the opposite edges of the strips rolled inwardand thread means for assembling the strips.

8. A napped knitted thread assembled rug embodying strips having thelongitudinal edges thereof rolled toward each other.

9. A rug of continuous strip drawn to a closed body and with the stripmargins folled thereinto to render the strips frayess.

10. A rug of continuous strips drawn to a closed body with the stripmargins rolled thereinto to conceal parallel fray edges and zig-zagthread means for assembling strips.

11. A rug of braided continuous strips of napped oneside knitted stocklongitudinally rolled into edge concealing contour.

' 12. A rug of braided continuous edge concealed strips of nappedone-side knitted stock and zig-zag thread means for assembling thestrips against fray edge exposure.

13. In the production of strip material from tubular fabric, thetransverse distension of said material, the longitudinal cutting of saidtransversely distended material, and the longitudinal distension of saidstrips for curling the edges thereof.

14:.
